CHARLES G. CONN, OF ELKHART, INDIANA.

CORNET.

SPECIFICATION forming part of Letters Patent No. 402,721, dated May *7, 1889.

Application filed October 30, 1886. Serial No. 217,605. (No model.)

To aZZ 2071.011?) it may concern.-

Be it known that I, CHARLES G. CONN, of Elkhart, in the county of Elkhart and State of Indiana, have invented an Improvement in Cornets, of which the following is a speeification.

My invention is an improvement in the connecting-pipes between the valve-cylinders. As heretofore constructed, these connectingpipes have been either both straight or both curved, or one of them curved and the other diagonal.

I11 my improvement I substitute a straight pipe for the curved pipein a curved and diagonal pipe-connection between the valves.

This improvement in construction makes the wind-passage more direct through the valves than with a curved and diagonal connection.

I11 order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawing,which represents in section longitudinally of the valve-cylinders aport-ion of a cornet embodying my improvement.

The cornet is constructed with customary air-pipe, A, valve-bends B, and valve-cylinders 1 2 3. Connecting the valve-cylinders are pipes D Dthe first straight, as shown, to present at (Z (1 right angles, while the second is made straight and arranged diagonallybetween the cylinders 2 3 from opposite the valve-opening to pipe D to opposite the valveopening to pipe A.

It will be observed that the position of the connectingpipes D D may be reversed from that here shown, the diagonal pipe D being arranged between the first and second valve cylinders and the straight pipe D between the second and third valve-cylinders.

This invention is applicable to other pistonvalve musical instruments as well as cornets.

Having thus described myinvention, the following is whatI claim as new therein'and desire to secure by Letters Patent:

1. In a cornet or other piston-valve musical instrument, the combination, with the valvecylinders, of a straight connection, D, between an outside valve-cylinder and the middle valve-cylinder, and a diagonal connection, D, between the other outside valve-cylinder and the middle valve-cylinder, substantially as shown and described.

2. The combinatiomwith the valve-cylinders 1 2 3, of a straight pipe-connection, D, between the first valve-cylinder, 1, and the second valve cylinder, 2, and a diagonal pipeconnection, D, between the second valve-cylinder, 2, and the third valve-cylinder, 3, substantially as described.
